1. A walker (1; 100) comprising a base frame (20) supported by wheels (22; 122) and support rods (3; 4) mounted on the said base frame (2) to support, at suitable height, support means (7; 8; 107) designed to support the patient while walking, wherein the support rods (3; 4) are hinged mutually and
1. A walker (1; 100) comprising a base frame (20) supported by wheels (22; 122) and support rods (3; 4) mounted on the said base frame (2) to support, at suitable height, support means (7; 8; 107) designed to support the patient while walking, wherein the support rods (3; 4) are hinged mutually and to the base frame (2), in such a way to go from an operating position, in which the support means (7; 8; 107) are at a suitable height to support the patient, to a minimum volume position, in which the support means (7; 8; 107) are near the base frame (2), wherein the support rods comprise at least a lower rod hinged by means of a hinge to the base frame and at least an upper rod hinged by means of a pantograph mechanism to the lower rod, wherein the rods (3; 4) respectively comprise an external pipe (32; 42) inside of which an internal pipe (33; 43) is extended, in which the ends of the internal pipes (33; 43) are connected to corresponding elliptical shells (34; 44) and the external pipes (32; 42) are connected mutually by a connection rod (9) to form the pantograph mechanism (40). 2. The walker (1; 100) as claimed in claim 1, wherein the hinge (30) comprises adjusting and lock means to adjust the inclination angle (.alpha.) (a) between the frame (2) and the lower rod (3). 3. The walker (1; 100) as claimed in claim 1, wherein the walker comprises lock means (5) between the lower rod (3) and the upper rod (4) to lock the two rods in position. 4. The walker (1; 100) as claimed in claim 3, wherein the lock means (5) comprise an assembly composed of a cylinder (50) and a piston (51). 5. The walker (1; 100) as claimed in claim 4, wherein an upper frame (6) is hinged at the upper end of the two upper rods (4), being provided with support means (7; 8; 107). 6. The walker (1; 100) as claimed in claim 1, wherein the base frame (2) is U-shaped and comprises two cross-pieces (20) connected by a transversal rod (21) and in that in the central part of the cross-pieces (20) corresponding lower rods (3) are hinged, which are in turn hinged to corresponding upper rods (4). 7. The walker (1; 100) as claimed in claim 6, wherein the upper frame (6) is U-shaped. 8. The walker (1) as claimed in claim 1, wherein the walker is a push walker and the support means (6, 7) comprise at least one openable padded ring designed to surround the patient's waist. 9. The walker (100) as claimed in claim 1, wherein the walker is a pull walker and the support means (107) comprise a handlebar designed to be grabbed by the patient. 10. A walker comprising: a base frame having wheels;a pair of lower rods each hingedly connected to the base frame;a pair of upper rods each hingedly connected to one of the pair of lower roads, the upper rods being hingedly connected to the lower rods by a pantograph mechanism; andan upper frame hingedly connected to pair of upper rods, the upper frame being height adjustable and having an operating position for supporting a patient and a minimum volume position, wherein each of the pair of lower rods respectively comprise an external pipe inside of which an internal pipe is extended, in which the ends of the internal pipes are connected to corresponding elliptical shells and the external pipes are connected mutually by a connection rod to form the pantograph mechanism. 11. The walker as claimed in claim 10, wherein the base frame comprises: at least two cross-pieces connected by a transversal rod; and each of the pair of lower rods are hingedly connected to a corresponding one of the at least two cross-pieces. 12. The walker as claimed in claim 11, wherein each of the pair of lower rods are connected to a central portion of the corresponding cross-piece. 13. The walker as claimed in claim 10, further comprising: a pair of assemblies each comprising: a cylinder; anda piston coupled with the cylinder,wherein each assembly of the pair of assemblies is connected between one hingedly connected upper rod and lower rod. 14. The walker as claimed in claim 10, wherein the hinged connection of one hingedly connected upper rod and the upper frame is positioned in a vertical axis with the hinged connection of a corresponding one hingedly connected lower rod and the base frame. 15. The walker as claimed in claim 10, wherein the hinged connection of a lower rod to the base frame is vertically aligned with the hinged connection of an upper rod to the support frame. 16. The walker as claimed in claim 10, wherein the upper frame is U-shaped. 17. The walker as claimed in claim 10, wherein the upper frame comprises at least one padded ring. 18. The walker as claimed in claim 10, wherein the upper frame comprises a handlebar.
